- CVE-2026-107705:
Poppler 0.42.0 through 26.10.0 contains a stack-based buffer overflow in Decrypt::revision6Hash() that allows attackers controlling the password to overwrite stack memory when opening AESV3/R6 encrypted PDFs. Attackers can supply a password longer than 127 bytes through applications using the libpoppler, libpoppler-glib or C++ API to overflow the K1 and E buffers, crashing the process or corrupting memory.
7 issues left for the package maintainer to handle:
- CVE-2026-93311:
(needs triaging)
A vulnerability was detected in Freedesktop Poppler 26.07.0. This issue affects the function SampledFunction::SampledFunction of the file poppler/Function.cc of the component SampledFunction. The manipulation of the argument BitsPerSample results in integer overflow. The attack may be performed from remote. The exploit is now public and may be used. The project was informed of the problem early through a bug report but has not responded yet.
- CVE-2026-93312:
(needs triaging)
A flaw has been found in Freedesktop Poppler 26.07.0. Impacted is the function JBIG2Stream::rewind of the file poppler/JBIG2Stream.cc. This manipulation causes null pointer dereference. It is possible to initiate the attack remotely. The exploit has been published and may be used. Upgrading to version 26.08.0 is recommended to address this issue. Patch name: 5e49250f13b0390edeb3f90eb4c02c9941f97067. Upgrading the affected component is advised.
- CVE-2026-93313:
(needs triaging)
A vulnerability was found in Freedesktop Poppler 26.07.0. The impacted element is the function JBIG2Stream::readCodeTableSeg of the file poppler/JBIG2Stream.cc. Performing a manipulation results in integer overflow. The attack can be initiated remotely. The exploit has been made public and could be used. The patch is named eb87cf711563894649bd0c365baa479401dc6d51. To fix this issue, it is recommended to deploy a patch.
- CVE-2026-93314:
(needs triaging)
A vulnerability was determined in Freedesktop Poppler 26.07.0. This affects the function FoFiTrueType::mapCodeToGID of the file fofi/FoFiTrueType.cc. Executing a manipulation of the argument segCnt can lead to integer overflow. The attack can be launched remotely. The exploit has been publicly disclosed and may be utilized. This patch is called ed2a5538cf0a8d3ff908191eda9b73f91a5f952a. It is advisable to implement a patch to correct this issue.
- CVE-2026-93653:
(needs triaging)
A denial of service flaw was found in Poppler's Splash backend. A crafted PDF with tiling-pattern geometry approaching the int32 boundary can cause SplashOutputDev::tilingPatternFill to compute an attacker-controlled repeat count that drives an excessively long loop in the pattern-fill scanline routine, without a corresponding memory allocation. An attacker could exploit this by supplying a malicious PDF to an application that renders it via Poppler's Splash backend, causing the rendering process to consume 100% CPU for an attacker-controlled, extended duration.
- CVE-2026-102620:
(needs triaging)
A vulnerability was determined in Freedesktop Poppler 26.06.0/26.07.0/26.08.0. This impacts the function FoFiTrueType::cvtSfnts of the file fofi/FoFiTrueType.cc. This manipulation causes integer overflow. The attack can only be executed locally. The exploit has been publicly disclosed and may be utilized. Patch name: 245d3c6823377755f2c1d5fdddd010279c6ed94d. It is suggested to install a patch to address this issue.
- CVE-2026-102621:
(needs triaging)
A vulnerability was identified in Freedesktop Poppler up to 26.08.0. Affected is the function SplashClip::clipToPath of the file splash/SplashClip.cc. Such manipulation leads to integer overflow. The attack can only be performed from a local environment. The exploit is publicly available and might be used. Upgrading to version 26.09.0 is able to address this issue. The name of the patch is 323c91036d99926a8b90dc14329f7b40aece22f8. It is recommended to upgrade the affected component.

2 ignored issues:
- CVE-2019-9543:
An issue was discovered in Poppler 0.74.0. A recursive function call, in JBIG2Stream::readGenericBitmap() located in JBIG2Stream.cc, can be triggered by sending a crafted pdf file to (for example) the pdfseparate binary. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact. This is related to JArithmeticDecoder::decodeBit.
- CVE-2019-9545:
An issue was discovered in Poppler 0.74.0. A recursive function call, in JBIG2Stream::readTextRegion() located in JBIG2Stream.cc, can be triggered by sending a crafted pdf file to (for example) the pdfimages binary. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact. This is related to JBIG2Bitmap::clearToZero.
